Definitions

  • the present invention relates to an apparatus for carrying out connection and disconnection of a circuit member, namely, a printed-board-shaped circuit such as an IC of LSI circuit package to an electrical connector.
  • a conventional connector is employed for mounting a board-shaped circuit such as an LSI package including a number of terminal pins on one surface thereof as shown in FIGS. 6 to 8.
  • the connector shown in these figures comprises a cover 5 and a base 7 which are made of insulating material.
  • a plurality of first pin holes 9 for allowing pin terminals 1 to be inserted therein is formed in the configuration of a matrix.
  • a number of second pin holes 13 for allowing the top end of each pin terminal 1 to be loosely inserted therein are also formed in the configuration of a matrix.
  • an apparatus for carrying out connection and disconnection of a circuit member to an electrical connector with the circuit member being moved in a first predetermined direction comprises an outer frame, an inner frame, a movable member, and driving means.
  • the outer frame is for holding the electrical connector.
  • the inner frame is for defining a space which is for containing the circuit member.
  • the inner frame is disposed inside the outer frame to be movable in the first predetermined direction with a gap left between the outer and the inner frames in the first predetermined direction.
  • the movable member is disposed in the gap and is movable in a second predetermined direction normal to the first predetermined direction.
  • the movable member is for moving the inner frame in the first predetermined direction dependent on movement of the movable member in the second predetermined direction.
  • the driving means is coupled to the outer frame and it is for driving the movable member in the second predetermined direction.
  • FIG. 1 is a plan view of an apparatus according to an embodiment of this invention, together with a board-shaped circuit which is cut off a part thereof;
  • FIG. 2 is an enlarged cross-sectional view taken on line II--II in FIG. 1;
  • FIG. 3 is an enlarged cross-sectional view taken on line III--III in FIG. 1;
  • FIG. 4 is an enlarged cross-sectional view of a portion A in FIG. 2;
  • FIG. 5 is an exploded perspective view of the apparatus in FIG. 1;
  • FIG. 6 is a perspective view of a conventional connector for use with board-shaped circuits, in which a board-shaped circuit has been incorporated;
  • FIG. 7 is a perspective view of the conventional connector for use with board-shaped circuits prior to the incorporation of the board-shaped circuit in FIG. 6;
  • FIG. 8 is a partial cross-sectional view of the conventional connector prior to the rotation of a crank lever in FIG. 6.
  • FIGS. 1 to 5 an apparatus according to an embodiment of this invention will now be explained.
  • the same reference numeral as in FIG. 1 designate identical or corresponding parts in FIGS. 6 through 8, and the explanation of the identical or corresponding parts is omitted.
  • the apparatus is for carrying out connection and disconnection of the LSI package 3 as a circuit member to an electrical connector 20 and includes an inner frame 21 and an outer frame 23.
  • the inner frame 21 is for defining a space which is for containing the LSI package 3.
  • the outer frame 23 is fixedly attached to a printed circuit board 19 via an insulating sheet 24.
  • the inner frame 21 is designed to be movable relative to the outer frame 23 only in a first predetermined direction (i.e., in the lateral direction in FIG. 1). Namely, gaps 25 are left between the inner and the outer frames 21 and 23 in the first predetermined direction.
  • the movement of the inner frame 21 can be carried out by moving a pair of wedges 27 incorporated between the outer frame 23 and the inner frame 21.
  • each of the wedges 27 is for moving the inner frame in the first predetermined direction.
  • the wedges 27 are movable only in a second predetermined direction (i.e., in the vertical direction in FIG. 1) normal to the first predetermined direction. Therefore, each of the wedges 27 is referred to as a movable member.
  • the inner frame 21 has end surfaces 21a which face the wedges 27 in the first predetermined direction, respectively.
  • Each of the end surfaces 21a extends in a particular direction which is slightly inclined to the second predetermined direction.
  • Each of the wedges 27 has a principal surface 27a which faces each of the end surfaces 21a of the inner frame 21 in the first predetermined direction.
  • the principal surface 27a extends in the particular direction.
  • Each of the wedges 27 is integrally fixed with a rack 29 at the upper surface thereof by a bolt 31.
  • the rack 29 extends along the upper surface of each of the wedges 27 in the second predetermined direction and is driven by a lever assembly 35.
  • the rack 29 has a plurality of teeth on a side surface thereof in the manner known in the art. Those teeth are arranged from end to end in the second predetermined direction. But a part of a group of the teeth is schematically depicted by a chain line in FIG. 5.
  • the lever assembly 35 comprises a shaft 32, a pinion 33, and a lever 34.
  • the pinion 33 is fixed to a lower portion of the shaft 32.
  • the lever 34 is held to an upper portion of the shaft 32.
  • the rack 29 and the lever assembly 35 in combination are collectively referred to as a driving arrangement.
  • the rack 29 engages with the pinion 33.
  • the rack 29 is held at a predetermined position by a rack guide 37 and a cover 39.
  • the rack guide 37 is secured to the outer frame 23 by a bolt 41.
  • the cover 39 is secured to the rack guide 37 by a bolt 42.
  • the rack guide 37 is for holding the pinion 33 to secure the engagement of the rack 29 with the pinion 33. Thereafter, the rack guide 37 is referred to as a holding arrangement.
  • a damper 43 and a return spring 45 are attached to each of the racks 29.
  • the return spring 45 is coupled to the rack 29 and the outer frame 23 and is for urging the rack 29 in the second predetermined direction.
  • the damper 43 is for absorbing an impact between the inner frame 21 and each of the wedges 27 in the manner known in the art.
  • the pin terminal 1 can be detached from the contact 11 by driving the lever assembly 35 on the left side in FIG. 1 so as to move the wedge 27 in the direction of an arrow 55.
  • the inner frame 21 is moved in the direction of an arrow 57 in accordance with the same principle as mentioned above.
  • the pin terminals 1 of the LSI package 3 are detached from the corresponding contacts 11.
  • the wedges are provided between the inner frame and the outer frame, and by moving the wedges, the inner frame is moved so that a connector is connected or disconnected with a small driving force even when the number of terminal pins of the connector is great.
